Consulting & advanced calculation services

At LTH-Baas, we provide a wide range of feasibility studies and technical consulting services to help shipowners make confident, cost-effective decisions on retrofit and upgrade projects for all types of vessels.

Our engineering team has supported clients with detailed feasibility analyses for projects including:

• Technical Feasibility Studies & Engineering Support
• Structural optimization
• Replacement studies for large machinery and equipment
• LNG retrofit conversions
• Energy efficiency retrofits
• Selective Catalytic Reduction – SCR – unit integrations onboard Floating Regasification Storage Units (FRSUs)
• Scrubber, EGCS integrations

These studies are backed by practical experience and data-driven assessments that reduce risk and improve project outcomes.

Vibration Measurement & Structural Damage Assessment

We conduct precise vibration measurements to identify abnormal behavior in ship systems and components.

When cracks or structural damage are detected, our engineers:

  • Diagnose the root cause
  • Develop tailored repair plans to address the issue at its source
  • Ensure long-term durability and reduce the risk of reoccurrance

Proper assessment is essential — without identifying the underlying cause, structural damage is likely to return even after repair.

Even the all-powerful Pointing has no control about the blind texts it is an almost unorthographic life One day however a small line of blind text by the name of Lorem Ipsum decided to leave for the far World of Grammar. The Big Oxmox advised her not to do so, because there were thousands of bad Commas, wild Question Marks and devious Semikoli.

Drydock Support & Efficiency Planning

Drydocking is a major cost center for shipowners — vessels generate no revenue while incurring docking and repair expenses.

At LTH-Baas, we help minimize drydock time through:

  • Thorough engineering preparation
  • Smart planning and sequencing
  • Coordinated procurement and logistics
  • Ready-to-execute designs that reduce onboard surprises

Our goal is to support efficient drydock operations that minimize downtime and maximize ROI.

Cracks in ship structure – Identification of root cause, and development of a repair plan.

Third-Party Design Reviews

Our design engineers offer independent design package reviews to help shipowners and operators avoid costly installation or maintenance issues later in the project.

We focus on:

  • Verifying installation and maintenance efficiency
  • Identifying potential risks, interferences, or design flaws
  • Ensuring compliance with industry best practices and class requirements

LTH-Baas adds value by uncovering hidden problems early — before they become delays or budget overruns.
