Saudi owner’s FSIV newbuild programme on track in Singapore

Singapore shipbuilder Lita Ocean has launched Zamil 81, the second of three 60-m fast support intervention vessels (FSIVs) for Zamil Offshore Services.

Being built to ABS class, Zamil 81 is an aluminium monohull vessel designed by Incat Crowther to provide a full load service speed of 25 knots and the 60-m by 9-m vessel can reach a maximum speed of 36 knots. The Australian ship designer reported the launch in a September social media post.

The first in the series, Panama-flagged Zamil 80, was delivered in Q2 2025 and is operating in the Arabian Gulf. The last two in the series will be handed over this year.

Each FSIV is powered by four MTU 16V4000 four-stroke diesel engines coupled to ZF gearboxes that drive Hamilton HT810 Waterjets.

Manoeuvrability of the DP2-certified vessels is enhanced by three Hydromaster tunnel bow thrusters, allowing safe docking and superior station-keeping for cargo and personnel transfers. Two of the main engines are coupled to FFS firefighting pumps with paired 1200 m³/hr water monitors and shipboard water spray protection offering FiFi-1 capability. Three Scania 300-kW diesel generators provide ship service power.

The vessels’ main deck offers an expansive 250-m² aft cargo deck rated at 2.5 tonne/m² and a climate-controlled forward cabin featuring business-class seating for 60 service personnel.

Saudi owner Zamil Offshore will use the FSIVs to transport cargo, heavy maintenance equipment and personnel for Saudi Aramco’s operations in the Arabian Sea.
