Hornbeck Offshore Services (HOS) is planning to invest $720m to build 16 offshore supply vessels (OSVs).
The OSV provider has contracted VT Halter Marine and Eastern Shipbuilding Group to build eight 300-class vessels, each with options to build additional such vessels.
Singapore-based VT Halter Marine has won $441m contract to build eight OSVs with an option to build an additional 24 OSVs.
The vessels will be DP-2 classed and based on the Super 320 design, they will have 6,200dwt capacity, approximately 20,900bbl liquid mud carrying capability, 11,863ft2 deck area and a fire-fighting class notation.
Delivery of the first vessel is slated for October 2013 with the eighth in September 2014, the company said.
The company currently owns 80 vessels that primarily serve the energy industry and will decide in September 2012 if it will exercise the options.
The company expects to place the first of the 16 vessels in service in the second quarter of 2013.
Delivery dates for option vessels will be approximately 26 months following the option exercise.
The other eight OSVs to be built by Eastern Shipbuilding will also be DP-2 classed; four vessels will be based on the STX Marine SV 300 design and four vessels will be based on the STX Marine SV 310 design.
