Lightning Naval Architecture (LNA) Ship Design and Naval Architecture for Conversions, Modernisations and Repairs


Lightning Naval Architecture (LNA) designs modernisations for existing vessels to extend their service-life and capacities.

We design complex conversions to re-purpose vessels and supervise the modifications, performing structural calculations and stability modelling to ensure your vessel complies with domestic or international rules and regulations.

We specify compliant materials for construction, and design ship-to-shore interfaces for loading and unloading of trains, trucks, and cars. In addition, we provide supervision and inspection services for ship-owners. We also design new vessels that are energy efficient.

Our services range from initial feasibility studies, transport analysis, budget estimates and concept designs to detail design, tendering and supervision both for new-buildings and for conversions and modifications. Our experienced naval architects and marine engineers employ an adaptive and methodical design process.

Ship design for transport, travel, freight haulage, and construction

LNA provides ship design and naval architecture services for Ro-Ro and rail passenger ferries, which transport freight and passengers by vehicles and rail. Applications include expedition cruise ships that journey to far-flung corners of the world, cargo vessels carrying containerised and bulk cargos and live animals, as well as infrastructure construction vessels used to building bridges, jetties, and ports.

A feasibility study and route analysis may be the first step if considering a new service. For modernisation of an existing vessel, often the first steps are a concept design and project cost estimates. This can be followed by preliminary design, budget preparation and materials specification through to design-for-construction plans and calculations and building supervision.

Full technical analysis can investigate hull form efficiency, propulsion effectiveness, and manoeuvring capability.

Ship structure designed for ease of building, structural repairs and rules compliance

LNA delivers efficient structural design outcomes to make the work of the shipyard or construction contractor straight-forward. We establish strong relationships with yards and related suppliers to enable your project to progress without unnecessary delay, also communicating throughout with classification societies and other accredited surveyors to progress the approval process smoothly.

We provide drawings and strength calculations for obtaining necessary approvals in preparation for structural repairs and for information to the shipyard doing the repair work.

Where appropriate, we analyse the cause of structural failures and investigate the most cost-effective repair options. Whether for new structures or repairs to existing you can rely on LNA to deliver a practical solution.

Ship modelling and analysis, stability for intact and damaged ships

LNA creates 3D computer models of large passenger vessels, special purpose and dry cargo ships to analyse their behaviour at-sea. Analyses regularly cover the areas of intact and damage stability, including optimisation of watertight sub-division.

We have considerable experience in carrying out probabilistic damage stability calculations to SOLAS 2009 and Special Purpose Ships (SPS) Code 2008 for Flag State approval.

Speed and power performance prediction, including propeller optimisation, are other tasks undertaken, as well as manoeuvring calculations and sea trials and sea-keeping analyses.

We have delivered specialised ship modelling and analysis on a variety of naval vessels in particular for the Royal New Zealand Navy. We use the world’s best commercial naval architecture software package, NAPA, for hull design, analysing intact and damage stability, speed and power, and manoeuvring.

LNA creates calculation models for stability analyses of the large barge and heavy machinery assemblages used in the construction of maritime infrastructure such as bridges, wharves, and ports. These analyses cover load-out and on-board operations of the heavy machinery, including crawler cranes, mobile drill rigs or tracked excavators, as well as delivery of load charts specific to maritime operations.

LNA can provide installation of and ongoing support for on-board stability software for intact and damage stability and longitudinal strength monitoring to client requirements and training of ships’ crew in-use of software and interpretation of outcomes.

On-board stability testing

LNA has extensive experience in carrying out SOLAS lightweight surveys and inclining experiments on large IMO-regulated Ro-Ro and special purpose ships, including in situations where there have been extensive modifications to the subject vessels. We have similar experience with NSCV-regulated commercial vessels, including both passenger and non-passenger vessels.

Compliance with International and domestic maritime regulations

SOLAS, Classification Society Rules, Australia’s National Standard for Commercial Vessels (NSCV): whatever the jurisdiction your vessel operates under, LNA can provide compliant solutions. We are also accredited by Australian Maritime Safety Authority for NSCV plan approval, stability approval and load-line assignment.
