Client: St. Christopher Air & Sea Ports Authority (SCASPA)
Value: $1 million
Project Date: 2013 - 2014

Located on the Basseterre coast, the Deep Water Port is the main cargo handling facility for St. Kitts, and can comfortably accommodate vessels over 900 feet long with a draught of 27 feet.  Vessels up to 300 feet can berth at the Ro-Ro pier which has a minimum depth of 19 feet. 

CASHMAN was contracted by the St. Christopher Air & Sea Ports Authority (SCASPA) to support its long-term strategy to further develop and modernize the cargo port of Bird Rocks to accommodate larger cruise ships visiting the islands of St. Kitts and Nevis. CASHMAN constructed a new breasting dolphin at the deep-water commercial port in Basseterre, St. Kitts. This dolphin made it feasible to berth eagle-class cruise ships at the commercial pier while the second pier was under construction. Additionally it provides a larger berth for increased capacity cargo ships. The dolphin is made up of seventeen 36-inch piles and has a 230-cubic-yard cap made up of reinforced 5,000 psi concrete. CASHMAN also constructed the temporary deck, rebar reinforcement cage, and form work for pouring concrete.


  • Construction services included driving piles into the seabed to gain compression strength and to provide a platform to cruise ships that were larger than the then-current berth at the cargo port, for breasting and mooring.
  • CASHMAN conducted the pile driving into bedrock depths; welding and testing of piles; and cutting of steel.
  • The infrastructure was designed so the dolphin could still be used as a breasting dolphin once the Bird Rock pier was developed and expanded.
  • Because the area was extremely busy, CASHMAN worked with SCASPA to keep mariners away from construction areas.
  • Work was completed in time for the spring 2014 cruise season.
