ENGINEERING MANAGEMENT

Managing a company’s engineering requires a difficult balance among many factors including cost, organizational learning, quality control, encouragement of creativity and innovation, development and retention of personnel. We can assist in the implementation of change control procedures, document control processes, ISO 9001 certification, enhancement of communication, interface management and all other aspects of engineering management in the project environment.

NAVAL ARCHITECTURE

Preliminary and basic design, feasibility studies and FEED studies.
Weights and centers calculations, parametric estimates by system from comparable projects, weight control and reduction innovation, ISO compliant procedures for tracking and predicting final weight outcomes during construction, hydrostatics calculations, stability calculations (intact and damaged), displacement and stability remediation and inlining experiments.
Resistance and propulsion, estimation of resistance from series tests, estimation of wake fraction and thrust deduction, propeller sizing, optimization and selection, bulb design, improvement of flow into propeller, model testing and sea trials.
Hydrodynamics, structural wave loading, vessel motions.

MARINE ENGINEERING

Equipment selection and specification.
Piping system design and analysis, material selection, wall sizing per ASME B31.1, pipe loss calculation, using PipeFlow, pump sizing and selection.
Propulsion system design, control systems, alarm systems and shafting detailed design.
Ventilation calculations, duct sizing and noise control.

PROJECT ENGINEERING MANAGEMENT

In our view, Project Engineering Management differs from Engineering Management due to the specificity of its application to one specific project or series of related projects. Engineering Management requires a longer term strategy, whereas Project Engineering Management a tight focus on the task at hand. We can enhance project performance through enhancing its Project Engineering Management effectiveness.

MOORING, RIGGING AND MECHANICAL HANDLING

Estimation of mooring loads, detailed design of mooring systems and components, single point mooring and temporary harbor mooring, using Orcaflex.

COST ESTIMATING, CONTRACT REVIEW, BIDS, PROPOSALS AND NEGOTIATIONS

We can assist with a specific opportunity or assist in implementing systems designed to produce attractive offers based on reliable cost estimates.

SHIPBUILDING

We have been involved in shipyard operations from lofting through sea trials and can advise on both the technical and commercial aspects of successful operation.

SHIPYARD FACILITIES PLANNING and DESIGN

Work flow, material availability and ease of access and handling can make a big difference in the competitive shipbuilding and repair business. We can evaluate your plans or existing operation to recommend improvements in layout, equipment or processes.
