Fourth 60-metre fast support intervention vessel commissioned after fleet’s exceptional performance

Offshore energy services provider Zamil Offshore has commissioned global digital shipbuilder Incat Crowther and Singaporean shipbuilder Lita Ocean to design, build and deliver a fourth 60-metre ABS-Classed monohull Fast Support Intervention Vessel (FSIV). The project follows the delivery of the third vessel in the original fleet with the exceptional performance of the fleet leading to the order of a fourth vessel.

The high-capable FSIV fleet is assisting Zamil Offshore with the efficient and safe transport of cargo, heavy maintenance equipment and personnel for Saudi Aramco’s operations in the Arabian Sea. The addition of a fourth vessel is an example of the confidence Zamil Offshore and their clients have in the vessel design and performance.

Capable of speeds up to 36 knots, the vessels are powered by four MTU 16V4000 diesel engines coupled to ZF gearboxes driving Hamilton HT810 waterjets. Manoeuvrability of the DP2-certified vessels is enhanced by three Hydromaster tunnel bow thrusters, allowing safe docking and superior offshore station-keeping for transfer of cargo and personnel. Two of the main engines are coupled to FFS firefighting pumps paired with 1200 m3/hr water monitors and shipboard water spray protection offering FiFi-1 capability. Three Scania 300kW diesel generators provide ship service power.

The main deck offers an expansive 250m2 aft cargo deck rated at 2.5 t/ m2 along with an optional Palfinger PK12000M deck crane. A climate-controlled forward cabin features business-class seating for 56 service personnel, as well as two bathrooms, a 15m2 workshop, a 15m2 storage room, a lounge and snack bar. The crew of 20 on the vessel are housed on the hull deck which features a large pantry, mess, three bathrooms and two laundry rooms.

The vessels comply with the latest MCVSR requirements from Saudi Aramco, including ABS SMART notation.

Incat Crowther Managing Director – North America, Grant Pecoraro said: “The commissioning of a fourth vessel is a strong endorsement of this platform’s performance, and of the operator’s trust in the build process following the on-time delivery of the original fleet. The project has been a true collaboration with the team at Lita Ocean, with our digital shipbuilding process derisking and streamlining the physical build process and complementing Lita Ocean’s approach. We look forward to continuing to support Zamil Offshore’s fleet expansion with this state-of-the-art design.”

Yeo Yingda, Director at Lita Ocean said: “Delivering the third vessel on schedule reflects the strength of our yard processes and the close working relationship we have with Incat Crowther. The fourth commission is a clear vote of confidence from Zamil Offshore in the partnership between Lita Ocean and Incat Crowther. We look forward to applying the same rigour to construction of this vessel and supporting the fleet’s continued expansion.”

The addition of a fourth vessel to the Zamil fleet builds on Incat Crowther’s track record of successful large fast monohull crew boat projects, with the global digital shipbuilder delivering a portfolio of over eighty (80) monohull crew boats for operators around the world.

Construction is now underway on the fourth vessel, with the vessel set to join its predecessors in service by 2027.
