How to Design a Ship

Arrangements, Hydrostatics, Mechanical, Piping, Structural

How to design a ship? How to go from a blank sheet of paper to a sensible design for a ship, when you have nothing to start with? So here are my secrets revealed.

Stability Letters Explained

Fluids, Hydrostatics, Integration / Engineering

For small vessels, the major problem with stability letters is explaining it to the captains. Today I will review a stability letter and give plain English interpretation of all the boring mumbo-jumbo.

Free Surface Moment

Fluids, Fluids Testing, Hydrostatics, Stability Test

The shifting liquid in a ship’s tanks can create a lethal scenario. For everyone's safety, learn about free surface moment.

Improve Engineering Value

3D Modeling, Arrangements, Drafting, Engineering Business, Fatigue, FEA / Numerical Methods, Fluid Dynamics, Fluids, Fluids Special Methods, Hull Structure, Hydrostatics, Structural

We all want to feel good about paying for engineering analysis. Sometimes the best answer drives us to maximize value, rather than minimize cost. In those cases, you do better to go beyond basic safety and search for enhancements. Today we discuss four engineering tasks where you can maximize your value. Extract every last drop of knowledge from your engineering project.

Stability Fails at Seakeeping

Fluids, Hydrostatics, Seakeeping / Fluid Structure Interaction

Stability and seakeeping are frequently misunderstood. To understand the limits of these sciences, we must unveil the motivation behind their development. How to guarantee ship safety on an uncertain ocean?

Video: Selecting the Right Hullform

Fluid Dynamics, Fluids, Hull Structure, Hydrostatics, Integration / Engineering, Production Engineering

Monohull, catamaran, trimaran . . . so many choices. Which hullform to pick? This article provides a rational and design map for selecting hullforms applicable to any type of mission.

GHS Tutorials: Macros and Scripting

Fluids, Hydrostatics

GHS is nothing without macros. They expand GHS into a repeatable and adaptable programming language. These FREE tutorials show you how.

Do We Have a Problem: Testing for List and Angle of Loll

Fluids, Hydrostatics

NEVER WASTE MONEY ON SPECIALISTS! Here are a few simple do-it-yourself tests to check for ship list and angle of loll.

Angle of Loll: Hidden Dangers to Stability

Fluids, Hydrostatics

PANIC! Angle of loll indicates serious stability problems. You need to track down this cause, because the next warning may be when your ship capsizes.
