Hornbeck Offshore Services, Inc. has announced the execution of definitive contracts for the construction of sixteen high-specification offshore supply vessels ("OSV"), in connection with its latest newbuild construction program announced on November 7, 2011.
This is the Company's eighth newbuild vessel program since its inception in 1997, and its fifth newbuild program involving state-of-the-art, technologically advanced new generation OSVs. The Company has separately contracted with VT Halter Marine, Inc. of Pascagoula, Mississippi and with Eastern Shipbuilding Group, Inc. of Panama City, Florida for the construction at each yard of eight 300 class vessels with options to build additional such vessels should future market conditions warrant. The Company's first decision with respect to the exercise of options will need to be made in September 2012. Delivery dates for option vessels will be approximately 26 months following the option exercise. The aggregate cost of the first sixteen vessels under this program is expected to be approximately $720 million, excluding construction period interest. Construction costs will be funded with cash on-hand (including the net proceeds of the Company's recently completed equity offering), projected free cash flow from operations and, if necessary, available capacity under the Company's currently undrawn and recently expanded $300 million revolving credit facility.
VT Halter Marine will construct eight vessels based on the Super 320 design that it developed for Hornbeck Offshore. These DP2 OSVs are designed to have 6,200 long tons of deadweight capacity, approximately 20,900 bbls of liquid mud carrying capability, 11,863 sq. ft. of deck area and a fire-fighting class notation. The Super 320 design is based on a larger version of the HOS Coral, an existing 290 class DP-2 OSV which the Company has successfully operated since her delivery in early 2009. The Super 320 design has been developed with particular attention to the most stringent regulations for environmental stewardship, including a double-hull that eliminates any fuel storage adjacent to the sideshell, and propulsion machinery that meets the requirements of EPA Tier 3 for stack emissions.
The eight OSVs to be constructed by Eastern Shipbuilding Group will be DP-2 classed and consist of four vessels based on the STX Marine SV 300 design and four vessels based on the STX Marine SV 310 design. Features of the STX design include over 20,000 bbls of liquid mud carrying capacity and a fire-fighting class notation. In addition, the SV 300 design calls for 5,500 long tons of deadweight capacity and 10,976 sq. ft. of deck space, while the SV 310 design calls for 6,144 long tons of deadweight capacity and 11,536 sq. ft. of deck space. The STX designs meet the same environmental standards mentioned above for the Super 320 design and will also carry the ENVIRO class notation by the American Bureau of Shipping.
Based on the schedule of projected vessel in-service dates the Company expects to own and operate 56 and 67 new generation OSVs as of December 31, 2013 and 2014, respectively. These vessel additions result in a projected average new generation OSV fleet complement of 52.2 and 62.8 vessels for the fiscal years 2013 and 2014, respectively. Inclusive of the vessel deliveries referred to below, the aggregate cost of the Company's fifth OSV newbuild program is expected to be approximately $720 million, of which $44 million, $227 million, $348 million and $101 million is expected to be incurred in 2011, 2012, 2013 and 2014, respectively.
