Preliminary Pontoon Design
On behalf of a major engineering house ONA undertook preliminary design of an inner harbour pontoon serviced by a system of gangways. The work required ONA to develop a preliminary structure, weight and stability estimates. ONA has significant experience designing and developing structural solutions for port facilities across the region. We are able to develop […]
Tanker Berthing Mooring and Risk Support
ONA were recently awarded a challenging mooring operational and technical scope supporting tanker offtake operations on a failed terminal mooring in a harsh marine environment in close proximity to shore. The scope required ONA to investigate and assess DP vessel supported berthing (live anchoring) at the berth including risk framing and evaluation of operability limits. […]
Slipway Cradle Concept Engineering
ONA recently completed a concept cradle design for slipping pilot boats and other craft on an isolated slipway in Australia’s North. The slip cradles were initially designed to be compliant with a specific vessel docking plan which due to the vessel length, necessitated significant support capacity along its keel. To enable smaller boat slipping the […]
Spread Moored Subsea Operations
ONA recently undertook a specialised mooring scope for a marine contractor who was planning spread moored subsea operations. ONA provided mooring and operational support that allowed the contractor to maximise their existing structural and mooring anchor capacities. Using OPTIMOOR, ONA was able to quickly identify environmental limitations for a quasi static mooring basis to determine […]
Container Stowage Optimisation and Voyage Support
ONA were requested to support container stacking and stowing diligence for a vessel operator recently. The scope required ONA to undertake container stacking calculations to classification society codes and requirements (BV and DNV) and develop utilisation strategies for the unique cargo particulars. Deviations from approved cargo securing manual and capacities require careful consideration and management […]
Electric Vessel Propulsion – Tourism
On behalf of a progressive marine tourism provider ONA has been providing significant support in building the foundations for electrically powered tourist vessels in Northern Australia. Consulting and building on our extensive marine design background in low resistance hulls and offshore electric power management system knowledge we have undertaken extensive research and feasibility studies into […]
