Tugnology 2019 Liverpool

09:00 - 18:00

Record numbers attend Tugnology 19 Liverpool

 

A record-breaking Tugnology 19 saw 405 delegates register for the unique in-depth technical conference about tugs and tugs alone held in Liverpool, UK.

 

Top level executive decision-makers and leading technological experts and innovators attended the two-day event at the ACC conference hall beside the River Mersey in the historic port city.

 

Among key themes discussed at Tugnology 19, organised by the ABR Company Ltd - publisher of International Tug & OSV, which also organises the industry-leading ITS Conventions around the world - was the importance of collaboration, which was highlighted by several speakers.

 

Inaugural speaker John Pearn made a strong case for better understanding between tug masters and pilots, including spending time on each other’s vessels. Pearn is a highly experienced marine pilot and is chairman of the UK Maritime Pilots’ Association and vice-president of the International Maritime Pilots’ Association. He told delegates that spending time on tugs had given him a better understanding of the issues faced by tug masters. “I would encourage tug skippers to go on a trip with pilots to see things from their perspective,” he urged.

 

Collaboration was also at the heart of the presentation by Dr Thijs Hasselaar, project manager at MARIN, who presented the findings of the joint industry project (JIP) on bollard pull (BP), set up to establish a common international standard for determining BP in trials. His paper was the culmination of four years of work among over 30 leading industry partners and class societies which was launched at Tugnology 15 in London with further meetings held at ITS 2016 in Boston, Tugnology 17 in Rotterdam and ITS 2018 Marseille.

 

The resulting standard has been agreed and will be available to adopt from 1 July, with several companies already committing to it.

 

The opportunities and challenges arising from the growth of big data were addressed in a trio of papers, followed by an extended joint Q&A session. Florus Wilming, of Netherlands-based Onboard, and Yilmaz Salman and Siebe Rooijakkers of Damen, spoke about industry applications of big data analytics, while Eva Peño, global market leader for OSV and tugs at Bureau Veritas, presented a thoughtful and thought-provoking paper on moving safely into the digital age, with particular reference to cybersecurity and the importance of contingency planning.

 

Safety was again a major theme at the conference with Robert Allan, executive chairman of naval architects Robert Allan Ltd, and Brendan Smoker, a mechanical engineer at the company, presenting a well-received paper entitled Escort Tug Safety: Accounting for Dynamic Scenarios.

 

Other subjects covered included ultrasound antifouling systems, towing rope connection technology, tug manoeuvrability and the latest in winch design and technology.


The concluding session ended the conference on a forward-looking note, with Tobias Oser of Schottel introducing the latest developments in mechanical hybrid tug design, and Tatsuya Ohno of Kawasaki Heavy Industries presenting a fascinating and well-received paper on the company’s plans and predictions for the future of tugboat propulsion.


Alongside the conference, 57 companies at the heart of the tug, towing and salvage industry had table-top displays of their latest products and innovations. Tugnology has always provided a platform for doing business, lots of business, and an ideal opportunity for networking with decision-makers, and this year was no exception, with many reporting a significantly more optimistic outlook than this time last year.

Garth Manson, managing director of The ABR Company Ltd, said: “We are absolutely delighted with how the event went. Once again, Tugnology has built on its previous success. I would like to thank all those who attended and took part, because this is your event. You are what makes it successful. I would particularly like to thank our sponsors and speakers, without whom the event would not happen.”

 

At Tugnology 19, Sanmar sponsored the welcome reception, IMS sponsored the early morning Run Crew; MTU all the coffee and tea breaks; Uzmar sponsored lunch on both days; Samson sponsored the pre-dinner drinks; Damen sponsored the dinner; Wärtsilä sponsored the delegates’ web app; JonRie sponsored the delegate lanyards and Caterpillar sponsored the conference photographer.

Opening and Inaugural Paper: Working Relationship between Tugs and Pilots

JOHN PEARN, Chairman UKMPA, UK Maritime Pilots’ Association, UK

 

International Standard for Bollard Pull Trials

DR THIJS HASSELAAR, Project Manager, Trials & Monitoring Department, MARIN (Maritime Research Institute Netherlands), The Netherlands

 

Over the past three years, MARIN, together with 30 leading industry partners and class societies, has developed an international standard for the execution of bollard pull trials. Through model tests, CFD and full scale trials, the factors affecting tug performance during a bollard pull have been thoroughly investigated. The results have been used to develop a proven methodology that will deliver reliable, repeatable and transparent BP performance values for tugs. The paper gives a summary of the trial standard developed in the Bollard Pull Joint Industry Project.

 

 

Monitor Tug Performance by Analysing Real-time and Sea-trial Data

SHERVIN YOUNESSI, enginei Technical Manager, Royston Ltd, UK

MIKE JUDD, Software Development Manager, Royston Ltd, UK

 

Digital evolution is currently taking place in the maritime industry to tackle the challenges of new regulations and energy efficient operations. This drives the industry to explore different energy efficiency measures such as hybrid propulsion, alternative fuels, remote operations and autonomy. This transformation also affects the tugboat industry where digitalisation of information has spurred the automation of existing processes and functions and has created a significant impact on operations. Vessels are becoming sophisticated sensor hubs to monitor different parameters. With advanced communication systems, ship connectivity is now improved to allow telemetry of an extensive volume of data. Big Data platforms will have an incredible effect on how vessels manage information and use real-time analytics for performance monitoring. A large amount of real-time data is generated from smart sensor networks and manual data from various sources, such as sea-trials. This paper demonstrates how data has been integrated and synchronised from multiple sources to monitor vessel performance.

 

 

Rosmanditen: A Theoretical and Experimental Insight into ASD Tug Manoeuvrability

LUCIA ENOIZI, Shipbuilding Engineer, Rosetti Marino SpA, Italy

BENEDETTO PIAGGIO, PhD Student, University of Genoa - DITEN - Naval Architecture and Marine Engineering, Italy

 

A co-operative research programme between Rosetti Marino shipyard and the Marine Technology Department of Genoa University has led to a new tug design, which embeds side damage survivability and low-to-high escort capabilities, as well as a simulation tool for evaluating the manoeuvrability of ASD tugs at high speed (escort) and low speed (harbour assistance) in a MATLAB-Simulink environment. The tool can simulate tug performance using different skeg sizes, propulsor sizes, engine powers and winch maximum tensions. The research programme involved the use of large towing tank tests, CFD simulations, the identification of manoeuvring and propulsion models, and full scale validation trials

 

Escort Tug Safety: Accounting for Dynamic Scenarios in Design and Operations

ROBERT ALLAN, Executive Chairman, Robert Allan Ltd, Canada

BRENDAN SMOKER, Mechanical Engineer, Robert Allan Ltd, Canada

 

Building on discussions at past Tugnology conferences, this paper examines dynamic scenarios possible during escort tug operations, including loss of towline, loss of thrust and transitional manoeuvres, and how they relate to present Class stability criteria based on zero-speed residual righting energy. This study demonstrates that 6 degree-of-freedom (6-DOF) manoeuvring simulation can be used to model such dynamic scenarios and proposes it as a tool to inform future work addressing Class criteria. The 6-DOF simulation tool readily predicts the coupled yaw/heel motion of a tug during escort, as well as wave-induced motions and the effectiveness of an active escort winch in reducing tension and tug motions. Finally, a collaborative path is proposed toward improving criteria for escort tug design and operations that account for ’real-world’ dynamics.

 

Moving Safely into the Digital Age

EVA PEÑO, Global Market Leader OSV & Tugs, Bureau Veritas Marine & Offshore, France

 

The time has come for the shipping industry to undergo its own digital transformation. Tugs - considering their function, operational profile and cost base - are well suited to take the next step. However, as much as digitalisation is a great opportunity to improve safety, reliability and to reduce costs, the industry will have to face up to the associated cyber risks. This paper will explain how these risks can be identified, analysed and assessed, and how appropriate mitigation measures can be defined to ensure safe onboard implementation of the new technologies.

 

Innovate Your Business Model by Using the True Power of Big Data Analytics

FLORUS WILMING, Founder & Director, Onboard, The Netherlands

 

The maritime industry is relatively advanced when it comes to technological progress. Automation is well-established, and vessels, platforms, ports and terminals are filled with sensors. However, the industry still lags behind in accepting new forms of digital technology. As the Internet of Things (IoT) increasingly weaves itself into our lives, nothing is stopping us from moving forward. We have all the opportunities we need to truly analyse how to use big data intelligently, and apply it to tug, towage, salvage and OSV business models and supply chains. We are ready to embark on this journey of digitalisation. This paper presents a case study on how to use big data to optimise terminal towage operations by Kotug Seabulk Maritime - a joint venture between Kotug International, Seabulk Towing and Buckeye Partners - at the Buckeye Bahamas hub in the Caribbean region and onboard.

 

Data Analytics in the Tug Industry: Operational Mode Identification of a Tug Based on Monitored Onboard Data

SIEBE ROOIJAKKERS, Senior Development Engineer, Damen Shipyards, The Netherlands

YILMAZ SALMAN, R&D Engineer, Damen Shipyards, The Netherlands

 

Staying at the forefront of the digital era, the use of remote monitoring to obtain and collect large amounts of data from real-life tug operations is ever more essential. Big data analysis helps understand equipment performance, allowing for operational fine-tuning and design improvement. This paper highlights promising areas of big data research at Damen, and the way in which these techniques are implemented to improve operational understanding and support, as well as vessel design. Multi-dimensional regression techniques are used to explore the correlation between, for example, fuel consumption and various operational parameters. These techniques constitute the cornerstone of benchmarking. Through connectivity and digitisation, we can become better acquainted with the operational side of our vessels: continuous monitoring of the vessel’s location and speed translates into a time-speed histogram; clustering and classification techniques use data from multiple sensors to automatically identify operational modes. A preliminary approach for condition based maintenance has been investigated by means of the analysis of measured vibrations, while machine learning techniques have enabled the identification of the key traits of a monitored system. The aforementioned topics are only a few examples of the multiple digital technologies that Damen is currently exploring, and that will positively impact the vessels of the future.

Advanced Variable Drive - Proven Technology for a Hybrid Age

CAPT GARY DOCKERTY, Sales Director MEA, Sanmar Shipyards, United Arab EmiratesTAMER GEÇKIN, Manager R&D and Special Projects, Sanmar AS, Turkey

 

Turkey-based Sanmar Shipyards has co-operated with Caterpillar Marine and Caterpillar dealer Borusan, in association with chief design partners Robert Allan Ltd of Canada, on a tugboat that incorporates a hydraulic ’hybrid’ propulsion system. The Cat Marine Advanced Variable DriveTM is a patented system leveraging Caterpillar’s extensive experience with integrated power systems technology. Sanmar, with over 40 years of experience in the tug building industry, is looking again to break new ground following on from being the world’s first builder of LNG powered tugs, as well as the builder of the world’s first commercial remotely operated vessel. This paper outlines the experience gained and outcomes achieved through this strategic development between Sanmar and Caterpillar. This is expected to provide a highly optimised, lower-cost alternative to conventional electric hybrid systems, with similar benefits regarding improved performance and lower emissions while maintaining a low noise profile. The system delivers the benefits of a variable-speed diesel electric propulsion (DEP) system, with additional potential benefits in cost and size.

 

The Modular Caliper Winch Concept

MARINUS JANSEN, Technical Innovations Manager, Rotortug BV, The Netherlands

 

Modern winch systems, such as render and recovery winches, have developed into overly complex pieces of machinery. The net result of this development is a fundamental disconnect between the winch design engineer’s construction goals, the end-user’s expectations, and stakeholder management. The modular caliper winch concept aims to simplify winch design and construction, while emulating advanced render and recovery functions, by using an advanced drive and brake control system and ’brute force’ principle functions. The innovative design will be an improvement for the industry with regard to its small footprint, reduced power consumption, improved control, easy maintenance, redundancy of key features, lack of gearbox, lower weight and safe emergency quick release option. This paper focuses on the modular winch concept, which breaks down the principal drive and brake systems into multiple redundant sub-systems, including an advanced dynamic control system to emulate high-end winch performance at similar or lower cost level. This technological development is a co-operative effort between Kotug International, Tugpins and Rotortug.

 

Integrated Propulsion Systems for the Tug Industry

JONAS L NYBERG, Product Manager, Marine Propulsion & Integration, Caterpillar Marine Solution Center, Sweden

 

Over the years, the importance of reducing installation costs for tugboats has grown in a market where competition between builders and operators is continuously increasing. Engines, propulsion and controls still represent a major part of the equipment cost of a vessel, and exist in a variety of configurations, all with their individual benefits. During the last few years, Caterpillar has introduced a series of integrated high speed engine and propulsion packages, with the goal of providing a simpler, more efficient solution to builders, designers and operators. This paper discusses the benefits of an integrated package, and how this can provide value to today’s competitive tug building industry.

 

Development of a Mechanical-Electric Hybrid ASD Tug

JONATHAN PARROTT, Senior Naval Architect, Jensen Naval Architects and Marine Engineers, USA

KRISTIAN EIKELAND HOLMEFJORD, Specialist Product Introduction, Kongsberg Maritime, Norway

 

For several years, Jensen has been working with Rolls-Royce on a mechanical-electric hybrid propulsion system for ASD tugs to boost available power to the thrusters. Currently under construction is a 100ft (30.5m) tug for Baydelta that utilises lower HP EPA Tier 3 main engines and an electric motor on each drive to maintain the same bollard pull rating as its sister ships. The propulsion system is designed so that the vessel will be able to transit and maintain station keeping using small auxiliary diesel generators and electric motors without the main engines running, reducing emissions as well as maintenance and operating costs.

 

Ultrasound: The Future of Antifouling Internal Cooling Systems and External Surfaces

DOMINIC FINDLOW, Technical Director, NRG Marine Ltd, UK

 

New environmental and invasive species regulations are compelling ship owners to adopt different systems and operational regimes to control the build-up of bio-fouling on the inside and outside of their vessels. In this paper, NRG Marine uses its experience from recent installations and the latest field research to look into the future of this fundamental part of tug operation, in advance of expected legislative changes towards negating the use of biocides.

 

The Vital Connection

JACCO VAN SNIPPENBERG, Group Lead Tug & Towing, Lankhorst Ropes, The Netherlands

 

This paper presents a timely review of towing line connections between main lines and pennants. Typically, towing rope configurations consist of various rope types, with different physical and mechanical characteristics. Understanding their strengths and weaknesses is important in ensuring safe and reliable connections, especially when connections need to be made quickly under challenging conditions during towing. In addition to examining in detail the different types of towline connections, the paper will consider the implications of new rope and connection developments. Throughout the review, the focus will be on reducing the cost of ownership without jeopardising safety.

 

The Mechanical Hybrid Tug: Utilising the Main Benefits of a Hybrid System Without Using a Complex Electric System or Stand-Alone Gearbox

TOBIAS OSER, Sales Manager Tug & Offshore Energy, Schottel GmbH, Germany

 

Across the globe, an increasing demand for fuel efficiency and reduced emissions can be recognised, especially for operations close to urban or environmentally protected areas. To meet this demand, tug operators can use hybrid or diesel-electric-powered vessels, with either batteries or combustion engines with exhaust gas treatment systems. However, only around 2 per cent of azimuth-thruster-powered tugs delivered between 2009 and 2019 use hybrid or full diesel-electric propulsion systems. One reason for this is the higher capital expenditure (Capex) and complexity of these systems. This paper will introduce a mechanical propulsion system that enables the operator to drive two thrusters with one combustion engine. The system is less complex and requires less capital expenditure, while also offering nearly the same major benefits as a hybrid system - namely, reduced fuel consumption, emissions reduction, increased mean time between outages of the main engines, and FiFi without using a separate FiFi pump engine or controllable pitch propellers.

 

The Kawasaki Proposal for Future Tugboat Propulsion

TATSUYA OHNO, Manager, Kawasaki Heavy Industries Ltd, Japan

 

Emissions requirements in harbour areas have recently been getting stricter. Batteries and LNG have been proposed as a means of solving this problem, but such technology requires much more investment than that involved in a conventional tugboat. In this paper, Kawasaki will propose a patent-pending new concept to resolve this issue. This scheme also addresses the issue of collaboration between the shore and vessels using electric power, as well as the labour shortage that is currently being faced in Japan.
