US-based Leevac Shipyards Jennings has secured a contract from Tidewater Marine to build two diesel electric platform supply vessels (PSVs) with an option to build two more vessels.
The PSVs will be built to Leevac Design Services (LDS) 300 DE design and will each have a length of 62ft, breadth of 62ft and depth of 24ft.
Each vessel will have a deadweight capacity of 5,400 LT and will be capable of carrying more than 17,600 barrels of liquid mud.
The PSVs will be equipped with four Caterpillar Model 3516C Tier 3 IMO II Marine variable speed diesel propulsion generator sets rated at 2,100kw each.
Propulsion drives and thrusters for the vessels will be delivered by Schottel, while Siemens will be responsible for providing its Bluedrive Plus C integrated electrical system, the first installation of the system on US-built PSVs.
Siemens’ Bluedrive Plus C systems are used to control power management, vessel control, machinery, alarms, power and propulsion systems.
Kongsberg Maritime will supply the DP-2 (dynamic positioning 2) systems for the new vessels, which will be built to ABS and USGC classifications.
Tidewater Marine has opted to class the vessel HAB (WB) and it will be ABS Classed with the A1 offshore support vessel (FFV-1) notation suitable for offship fire-fighting capabilities.
According to Leevac, the new PSVs will be the seventh and eighth Leevac-designed vessels to be built for Tidewater.
Tidewater vice president for engineering and technical services Billy Brown said: "Tidewater has added more than 200 new ships to its global fleet over the last ten years, with vessels built in both US and international shipyards."
Leevac is currently building two Z-Tech 2400 Class Escort Tugs for G & H Towing Company, one MMC 879 PSV for Tidewater Marine and two LDS 270 DE PVS for Aries Marine.
