The 300’ LOA diesel electrics PSVs will be built at LEEVAC’s shipyards in Louisiana. “We are very excited to have another opportunity to build for Tidewater. This marks the seventh and eighth LEEVAC designed vessels to be built for them.” said Christian Vaccari, President of LEEVAC.
The LDS 300 DE PSV will have a deadweight capacity of 5400 LTs and will carry over 17,600 barrels of liquid mud. It will be powered by four Caterpillar Model 3516C Tier 3 IMO II Marine variable speed diesel propulsion generator sets rated at 2100kw each. The propulsion drives and thrusters are being provided by Schottel. Tidewater chose Siemens as the vendor for the Integrated Electrical System. These will be the first US built PSVs to be outfitted with Siemens’ BLUEDRIVE Plus C™ systems used to control the power management, vessel control, machinery, alarms, power and propulsion systems.
The vessel will be built to ABS and USGC classifications. Additionally, Tidewater has chosen to class this vessel HAB (WB) and the vessel will be ABS classed with the A1 Offshore Support Vessel (FFV-1) notation for offship fire fighting capabilities. “I have worked with the the team at Tidewater for years”, said Mike Jannise, Engineering Manager at LEEVAC. “These guys know what they want and it makes designing a vessel of this quality level a very exciting project for us.”
Billy Brown, Tidewater’s Vice President for Engineering and Technical Services, said “Tidewater is pleased again to have the opportunity to work with the LEEVAC design and new construction teams. Tidewater has added more than 200 new ships to its global fleet over the last 10 years, with vessels built in both U.S. and international shipyards. We have consistently found that LEEVAC designs and builds a fine ship.”
According to LEEVAC activity in Gulfcoast shipyards has significantly increased and the availability for shipyard slots is starting to disappear.
