Construction has commenced in east Asia on the first of a pair of dual-fuel harbour tugs, to be delivered next year for ship handling operations in Singapore.
PaxOcean Engineering laid the keel for the first of these LNG-powered harbour tugs at its facility in Zhuhai, China, on 23 November. This vessel, known by its hull number PX1098, and its sister tug, will be operated by PSA Marine.
To meet PSA Marine’s performance, stability and environmental leadership expectations, PaxOcean selected Canadian naval architect Robert Allan to design these dual-fuel tugs in January this year.
Robert Allan already has experience in designing LNG-powered tugs, having designed three RAstar 4000-DF tugs for Østensjø Rederi, Norway and one RAstar 3800-DF for Ningbo Port, China.
This designer has a relationship with the owner as it designed the Z-Tech series of tugs for PSA Marine’s operations in 2002.
PaxOcean has built other diesel-powered harbour tugs in China for PSA Marine this year. In September it delivered two escort and berthing support tugs to PSA Marine in Singapore. These azimuthing stern drive (ASD) tugs, PSA Thor and PSA Hulk, were built to the same Robert Allan design and are classed by Lloyd’s Register.
The group is also building eight harbour tugs for Formosa Plastics subsidiary Mailiao Harbor Administration Corp at its facilities in Indonesia for 2020 delivery and operations in Taiwan.
PSA Marine has also taken delivery of a batch of Z-Tech azimuth stern drive tugs from Cheoy Lee shipyards this year. This included three Z-Tech 5000 tugs, with a new deckhouse and wheelhouse design, in Q3. Two were for PSA Marine’s operations and a third for South China Towing of Hong Kong.
