Overview

We provide a comprehensive design and engineering package for owners undertaking vessel refits or conversions

A well-executed ship conversion is a cost-effective method of extending the life and repurposing an existing vessel. Having completed over 300 conversions, KNUD E. HANSEN has extensive experience in this field. Our portfolio includes dimension/capacity changes, vessel life extensions, repurposing, regulatory changes, accommodation refurbishment and energy saving projects.

Our scope covers the entire conversion process from initial feasibility studies and yard tendering through to on-site support and supervision during fabrication.

Design phases

KNUD E. HANSEN provides design solutions for all types of marine vessels and offshore structures.
  • Design & consultancy
  • Concept Design
  • Tender/Contract Design
  • Optimised Basic Design
Design & consultancy

Our expertise encompasses the whole range of design activities, including:

  • Creative and innovative concept design
  • Optimised basic design based on regulatory and client requirements
  • Integration and coordination of detail design

At KNUD E. HANSEN our design, consultancy and technical support services extend throughout the lifetime of a vessel or offshore structure. Starting at the conceptual design stage and continuing through construction to maintenance and conversion, we provide all the disciplines within naval architecture and marine engineering required to successfully undertake every aspect of even the most complex marine projects.

Working in close cooperation with our clients we use a staged approach, designed to minimise risk exposure and costs for all the parties concerned.

Concept Design

We start each new refit or conversion project with a Concept Design. Here, we explore ideas consistent with the client’s objective to extend the life of the vessel while possibly changing its operational profile, modifying vessel particulars, or repurposing certain spaces. These design options are explored while keeping the client’s requirements and budget firmly in mind. Using our vast experience and portfolio of refit and conversion projects, we narrow down a range of ideas and the project starts coming to life.

Tender/Contract Design

With a Concept Design selected, we proceed to Tender/Contract Design. At this phase the client (a shipyard or owner) engages us to further develop the concept to the point at which the yard can use it to calculate a firm price to present to the owner and enter into negotiations. During this phase and prior to the owner signing the final contract, we can also undertake additional services including:

  • Contract negotiations
  • Planning and cost evaluations
  • Purchasing and procurement support
  • Shipyard assessment
  • Supplier evaluation and selection
  • Reviews of third party designs, specifications and contracts
Optimised Basic Design

At this point the design is optimised based on the requirements of both the client and the relevant regulatory bodies. This will ensure that the design complies with the designated Classification Society and Flag State.

Our capabilities and resources also enable us to offer the following services during this phase:

  • Plan approvals
  • Project and contract management
  • Sea trials and delivery
  • Site supervision and inspection as owner’s representative
  • Site supervision and technical support on behalf of the shipyard

Customised solutions

Our solutions are tailored exactly to your needs. Our unique approach is based on the free exchange of ideas with our clients, a drive for continual innovation and years of experience encompassing every kind of vessel. Combining these elements, we apply fresh thinking to each new project, tailoring solutions that are both state-of-the-art, practical and that meet the individual needs of our clients exactly.

At the cutting-edge of ship design

We employ the most up-to-the-minute software and techniques for the development of 2D and 3D designs, FEM and CFD models, advanced structural design and intact and damage stability calculations. We maintain relationships with the world’s leading research institutions in order to facilitate in-depth research and model testing.

We have developed a completely new technology. This technology – Virtual Reality (VR) Design Verification Tool – makes it possible to take customers on a virtual tour inside new ships before construction has even begun, or first steel is cut.

Through lifecycle support

Our support does not end after design delivery. During a newbuild project, we are able to supervise throughout the entire programme, on behalf of the client. Subsequent to delivery, we are on-hand to review the technical, operational and commercial performance of the vessel and to provide modification and upgrade solutions in line with both client requirements and newly implemented regulations.

The design and engineering of refit & conversion projects is also a core activity at KNUD E. HANSEN, so we are able to give your existing vessels a new lease on life or prepare them for alternative application.

Our combined expertise in design and engineering allows us to deliver energy efficiency solutions through the optimisation of every aspect of a newbuild and its systems.

Our research activities are conducted on behalf of a diverse client range across both private and public sectors. The fact that KNUD E. HANSEN has carried out projects in so many segments of the maritime sector, all over the world, gives our research scope the broadest possible reach.
