This paper presents the design challenges of the new Seward Marine Center Marine Facilities project. The proposed facilities will serve as the home port for the R/V Sikuliaq, a 261-ft oceanographic ice-capable research vessel. The facilities include two berths at an open pile fixed pier and a single berth at the seawall. A wave barrier wall is fixed to the pier to provide safe berthing of the vessels in the basin. Several layouts were investigated for the orientation of the facilities to provide optimal vessel accessibility. The pier structural design considers inertial, and liquefaction induced kinematic load per ASCE 61, as well as the incidental wave load on the barrier wall for 100-year return period event. Geotechnical investigation indicates ground improvement is recommended behind the seawall due to potential soil liquefaction.
